A cable duct plug with locking mechanism

Abstract

This utility model relates to the field of pipe fittings technology, and in particular to a cable duct plug with a locking mechanism. It includes a cable duct, an installation assembly, a locking assembly, and an annular silicone block. In this utility model, through the use of a threaded sleeve, adjusting bolt, ejector slider, locking slider, and transmission plate, the device can drive the transmission shaft and locking plate forward via the threaded sleeve and adjusting bolt. This causes the transmission plate to apply a forward force to the ejector slider, locking slider, and installation plate. This allows the locking slider to clamp the cable duct in conjunction with the installation shell, and also causes the annular silicone block to deform under pressure. The device can automatically lock the installation plate and cable duct while applying pressure to the annular silicone block, preventing relative movement between the locking assembly and the cable duct when subjected to external force, and avoiding excessive friction and damage to the annular silicone block. This fixing method is simple and quick to operate, making the installation and removal of the plug time-saving and labor-saving.

Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, specifically a cable pipe plug with a locking mechanism. Background Technology

[0002] Cable duct plugs are important equipment used in the power distribution network field. They are mainly used for plugging and sealing cable ducts. They consist of a flexible silicone part and pressure plates at both ends. They are fixed by screws and pressure is applied, causing the outer ring of the flexible silicone part to expand and press against the inner wall of the duct, while the inner ring tightens and hugs the cable, achieving isolation and sealing between the inside and outside of the duct. They can be repeatedly disassembled and reassembled, and have the functions of sealing and waterproofing, and preventing debris and small animals from entering.

[0003] Some existing cable duct plugs lack an automatic locking mechanism, requiring manual fixing of the plug to the duct end with bolts to prevent relative movement between the plug and the cable duct when subjected to external force, which could cause excessive friction and damage to the flexible silicone parts. This fixing method is cumbersome and makes the installation and removal of the plug time-consuming and labor-intensive. Therefore, to address the above problems, a cable duct plug with a locking mechanism is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a cable duct plug with a locking mechanism to solve the problem that some existing cable duct plugs require manual fixing of the cable duct plug to the end of the duct with bolts.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable duct plugging device with a locking mechanism includes a cable duct, an installation assembly, a locking assembly, and an annular silicone block. The installation assembly is located at the front end of the cable duct. The installation assembly includes an installation shell. Threaded sleeves penetrating the front end plane of the installation shell are fixedly connected to both the left and right halves of the installation shell. Adjusting bolts are threaded into the interior of each threaded sleeve. A drive shaft is fixedly connected to the rear end of each adjusting bolt. A locking plate is fixedly connected to the rear end of each drive shaft. The locking assembly includes a mounting plate located inside the cable duct and penetrated by two drive shafts. Two positioning shafts penetrating the installation shell are fixedly connected to the front side of the mounting plate. Two first sliding grooves are formed on the rear side of the mounting plate. Second sliding grooves, communicating with the front sides of the first sliding grooves, are formed at both the upper and lower ends of the mounting plate. Ejector sliders are slidably connected in each of the first sliding grooves, and locking sliders are slidably connected in each of the second sliding grooves. A drive plate penetrated by the two drive shafts is located on the rear side of the mounting plate. An annular silicone block, penetrated by the drive shafts and positioning shafts, is located between the mounting plate and the installation shell.

[0007] Preferably, the ejector sliders are all composed of rectangular blocks and trapezoidal blocks, and trapezoidal grooves are provided on the opposite sides of the locking sliders. The trapezoidal blocks of the ejector sliders are all located in the trapezoidal grooves provided by the locking sliders and are slidably connected to the locking sliders.

[0008] Preferably, the outer side of each adjusting bolt is threaded with a reinforcing nut located in front of the threaded sleeve, the outer diameter of the adjusting bolt is equal to the diameter of the drive shaft, and the front side of the locking plate and the rear side of the drive plate are in contact.

[0009] Preferably, the mounting shell is composed of a circular tube and an annular plate, wherein the inner diameter of the circular tube of the mounting shell is equal to the outer diameter of the cable conduit, and the outer diameters of the mounting plate and the transmission plate are both equal to the inner diameter of the cable conduit.

[0010] Preferably, the outer diameter of the annular silicone block in its natural state is equal to the inner diameter of the cable conduit, and the inner diameter of the annular silicone block in its natural state is smaller than the inner diameter of the mounting plate and the transmission plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the device, through the threaded sleeve, adjusting bolt, ejector slider, locking slider, and transmission plate, can drive the transmission shaft and locking plate forward via the threaded sleeve and adjusting bolt. This causes the transmission plate to apply a forward force to the ejector slider, locking slider, and mounting plate. This allows the locking slider to clamp the cable conduit in conjunction with the mounting shell, and also causes the annular silicone block to deform under pressure. The device can automatically lock the mounting plate and cable conduit while applying pressure to the annular silicone block, preventing relative movement between the locking assembly and the cable conduit when subjected to external force. This avoids excessive friction and damage to the annular silicone block. This fixing method is simple and quick to operate, making the installation and removal of the sealing device more time-saving and labor-saving. Attached Figure Description

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] A cable duct plugging device with a locking mechanism includes a cable duct 1, an installation assembly 2, a locking assembly 3, and an annular silicone block 4. The installation assembly 2 is located at the front end of the cable duct 1. The installation assembly 2 includes an installation shell 21. Threaded sleeves 22 penetrating the front end plane of the installation shell 21 are fixedly connected to both the left and right halves of the installation shell 21. Adjusting bolts 23 are threadedly connected inside the threaded sleeves 22. A drive shaft 24 is fixedly connected to the rear end of each adjusting bolt 23. A locking plate 25 is fixedly connected to the rear end of each drive shaft 24. The locking assembly 3 is located on the rear side of the installation shell 21. The locking assembly 3 includes components located inside the cable duct 1 and... The mounting plate 31 is penetrated by two drive shafts 24. Two positioning shafts 32 are fixedly connected to the front side of the mounting plate 31 and pass through the mounting shell 21. Two first sliding grooves 33 are opened on the rear side of the mounting plate 31. The upper and lower ends of the mounting plate 31 are provided with second sliding grooves 34 that communicate with the front side of the first sliding grooves 33. An ejector slider 35 is slidably connected in the first sliding groove 33 and a locking slider 36 is slidably connected in the second sliding groove 34. A drive plate 37 is provided on the rear side of the mounting plate 31 and penetrated by the two drive shafts 24. An annular silicone block 4 is provided between the mounting plate 31 and the mounting shell 21 and is penetrated by the drive shafts 24 and the positioning shafts 32.

[0025] The ejector sliders 35 are all composed of rectangular blocks and trapezoidal blocks. Trapezoidal grooves are provided on the opposing sides of the locking sliders 36. The trapezoidal blocks of the ejector sliders 35 are located within the trapezoidal grooves of the locking sliders 36 and are slidably connected to the locking sliders 36. The ejector sliders 35 can push the locking sliders 36, causing the two locking sliders 36 to slide up and down along the second slide groove 34 respectively. The outer side of the adjusting bolts 23 is threaded with a reinforcing nut 26 located in front of the threaded sleeve 22. The outer diameter of the adjusting bolts 23 is equal to the diameter of the drive shaft 24. The front side of the locking plate 25 and the rear side of the drive plate 37 are in contact. A forward force can be applied to the transmission plate 37; the mounting shell 21 is composed of a circular tube and a circular annular plate. The inner diameter of the circular tube of the mounting shell 21 is equal to the outer diameter of the cable conduit 1. The outer diameters of the mounting plate 31 and the transmission plate 37 are both equal to the inner diameter of the cable conduit 1. The mounting plate 31 and the transmission plate 37 can move back and forth inside the cable conduit 1; the outer diameter of the annular silicone block 4 in its natural state is equal to the inner diameter of the cable conduit 1. The inner diameter of the annular silicone block 4 in its natural state is smaller than the inner diameters of the mounting plate 31 and the transmission plate 37. When the annular silicone block 4 is squeezed and deformed, it can fill the gap between the cable conduit 1 and the cable.

[0026] Working process: The inner diameter of the circular tube portion of the mounting shell 21 of this device is determined by the outer diameter of the cable conduit 1. The outer diameters of the mounting plate 31 and the transmission plate 37, and the outer diameter of the annular silicone block 4 in its natural state, are determined by the inner diameter of the cable conduit 1. The inner diameter of the annular silicone block 4 in its natural state is equal to the diameter of the cable. This device can produce different models of equipment to match cable conduits 1 of different diameters. Before use, the appropriate equipment diameter can be selected based on the outer diameter, inner diameter of the cable conduit 1, and the diameter of the cable. The manufacturing processes of the mounting shell 21, mounting plate 31, transmission plate 37, and annular silicone block 4 are all existing technologies. When using this device, the operator first places the mounting shell 21 over the outer side of the front end of the cable duct 1 from front to back, ensuring a certain gap between the front end of the cable duct 1 and the rear side of the annular plate of the mounting shell 21. Then, the operator simultaneously turns the adjusting bolts 23 with both hands, causing the two adjusting bolts 23 to rotate synchronously in opposite directions. This allows the adjusting bolts 23 to move forward along the threaded sleeve 22. The adjusting bolts 23 drive the transmission shaft 24 and the locking plate 25 to move together. The locking plate 25 applies a forward force to the transmission plate 37, which in turn applies a forward force to the ejector slider 35, moving it forward along the first slide groove 33. The sliding ejector slider 35 can push the locking slider 36, causing the two locking sliders 36 to slide up and down along the second groove 34 respectively. The locking sliders 36 then protrude from the second groove 34. The opposite sides of both locking sliders 36 are curved surfaces with a curvature equal to the inner diameter of the cable conduit 1. The locking sliders 36 can hold the inner diameter of the cable conduit 1 in place. The locking sliders 36, in conjunction with the mounting shell 21, clamp the cable conduit 1, thus stably fixing the mounting plate 31 inside the cable conduit 1. Simultaneously, the ejector slider 35 and the locking slider 36 can apply a forward force to the mounting plate 31. Because the locking slider 36 holds the cable conduit... After the cable duct 1 is blocked, the mounting plate 31 cannot move back and forth relative to the cable duct 1. Therefore, the mounting shell 21 will move backward under the action of the threaded sleeve 22. Thus, the mounting plate 31 and the mounting shell 21 can squeeze the annular silicone block 4 located inside the cable duct 1. The annular silicone block 4, which is passed through by the drive shaft 24 and the positioning shaft 32, is squeezed and deformed, which can fill the gap between the cable duct 1 and the cable, and achieve the isolation and sealing of the cable duct 1. Then, the workers rotate the two reinforcing nuts 26 respectively, so that the rear side of the reinforcing nut 26 and the front side of the threaded sleeve 22 fit together, which can lock and reinforce the adjusting bolt 23.This device can drive the drive shaft 24 and locking plate 25 forward via the threaded sleeve 22 and adjusting bolt 23. This causes the drive plate 37 to apply a forward force to the ejector slider 35, locking slider 36, and mounting plate 31. This allows the locking slider 36 to clamp the cable conduit 1 in conjunction with the mounting shell 21, and also causes the annular silicone block 4 to deform under pressure. Simultaneously, the device can automatically lock the mounting plate 31 and cable conduit 1 through the locking slider 36 while applying pressure to the annular silicone block 4. This prevents relative movement between the locking assembly 3 and the cable conduit 1 when subjected to external force, avoiding excessive friction and damage to the annular silicone block 4. This fixing method is simple and quick to operate, making the installation and removal of the sealing device time-saving and labor-saving.
